Paperkiller,

As followup, are your "go-to" rifles, semi-autos by any chance? The CCI #41's were designed to prevent slam fires in semi & full auto weapons, thus the tougher cup material.

Have the firing pin springs been replaced?

What other powders have you successfully used in these rifles?

As also mentioned, once you start piercing primers, firing pin erosion will make the problems even worse.

As you can tell, there are a number of things that could be causing the problem, and several possible solutions.
